D&R's Air Conditioning & Heating | Top-Rated HVAC Repair in Marion, TX

This is a common issue in our Texas climate, often caused by dirty condenser coils restricting airflow, low refrigerant levels, or a failing capacitor. Our technicians first perform a thorough inspection to pinpoint the exact cause—whether it's a simple cleaning, a refrigerant recharge, or a part replacement—to get your system cooling reliably again and prevent further damage.

Intermittent thermostat problems are frequently due to faulty wiring connections, old batteries, or a thermostat location that's affected by direct sunlight or drafts. We'll check the wiring at both the thermostat and the HVAC unit, ensure proper placement, and recommend an upgrade if needed, restoring accurate control and comfort to your home.

First, check your circuit breaker and replace the thermostat batteries. If that doesn't work, it likely indicates a deeper electrical issue, such as a blown fuse in the air handler or a wiring fault. Don't attempt to rewire it yourself. Call us for a safe diagnosis and repair to restore power and communication between your thermostat and system.
